Comparing the clinical profiles, pharmacokinetic behaviors, and safety indices of these two therapeutic agents.
Cefazolin is a first-generation cephalosporin antibiotic that inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), thereby disrupting peptidoglycan cross-linking.
Ceftazidime inhibits bacterial cell wall synthesis by binding to penicillin-binding proteins (PBPs), primarily PBP-3, leading to cell lysis and death. It is a beta-lactam antibiotic with activity against Gram-negative bacteria including Pseudomonas aeruginosa.
1-2 g IV every 8 hours. For serious infections, up to 2 g IV every 6 hours.
1-2 g intravenously every 8 hours for most infections; up to 2 g every 6 hours for severe infections, particularly in neutropenic patients or those with cystic fibrosis.

1.8 hours in normal renal function. Prolonged to 12-24 hours in end-stage renal disease (CrCl <10 mL/min).
Terminal elimination half-life 1.7-2.0 hours in adults with normal renal function; prolonged to 12-30 hours in end-stage renal disease.
Renal: 80-90% unchanged by glomerular filtration and tubular secretion. Biliary: minor (<1%). Fecal: negligible.
Primarily renal (80-90% unchanged via glomerular filtration and tubular secretion); biliary/fecal excretion accounts for <1%.
